Welcome to viyas LK Inter, our product is Yttria Stabilized Zirconia Bead (EZ-bead) & Zirconia powder (EZ-powder) . Our company is set up to provide zirconium with high quality (you can see the test report comparing to Japan leading brand) but reasonable price. The success and growth of our company is the result of responding to customer's needs and delivering the right material. It's convenient for you to find us on the internet. ( http://www.wowzen.com/ )

The advantage of our zirconia bead (EZ-BEAD)

High Dense‧Small Grain Size
Near nano zirconia powder is used for the grinding beads to achieve almost theoretical density, hardness and toughness. Together with special forming process, our YSZ beads have superior micro-structure and physical properties which provides extreme wear resistance and life-time for high speed milling process.

Always Shiny Surface Condition
Shiny surface throughout life-time results from high dense internal structure and stable chemical composition. It reduces friction between bead-bead and bead-grinding chamber which benefits temperature control, energy saving, and avoiding damage of the chamber inner wall. On the other hand, always shiny beads are easy to clean which provides time saving when changing product lines and minimizes cross contamination as well.

Superior Roundness and Narrow size distribution
Size distribution and roundness of the beads play the key contribution of milling efficiency.Our YSZ beads, with roundness
over 96% and precise sieving size control, provides best the milling efficiency.

Purpose : To analyze the beads (Ceno bead from famous Korea bead maker ) that sent by customer
Brief :
Compare with beads that provided by LK Inter, customer’s sample ( Ceno-bead) has poor density and crushing load which will lead to bead breakage during high speed milling. This is due to “hole” inside the bead body.
The surface condition and roundness of beads that provided by customer are also much worse that that by LK Inter. Poor surface smoothness and “egg-like” beads tend to cause high friction which results in high wear of the machine and high temperature of the milling slurry.
Beads provided by LK-Inter has wider distribution than customer’s. It is due to the distribution can be controlled by sieving , it can be adjusted.

Our government also recognized the importance and they are currently promoting several major policies including R&D, facilities construction, personnel training and so forth followed by "National General Nano Technology Development Plan(July, 2001)" as well as operating "The National Program for Tera Level Nanodevices".

Nano technology R&D, however, requires inter-disciplinary working/research with otherwise subjects such as physics, chemistry and material engineering beyond the existing research practices led by individual researches on electronics or physics and it should be supported by plentiful financial investments. While the leading country of Nano technology, America supports its source technology development to the level commercial businesses may be interested in, we may address "selection and concentration" reflecting limited resources and personnel as one of late countries to develop it.

In the middle of the above situation, Nano Technology Research Association(NTRA) was established on December 12, 2001. The association sets up the following objects to facilitate the development of membership companies, to improve domestic industrial Nano technology and to strengthen international competitiveness.

Firstly, the association facilitates active participation of industries by increasing the effectiveness of the governmental Nano technology policy, structures cooperation system of industry/academy/research institute and inter-works Nano technology in various fields, creating the synergy effect.

Secondly, the association connects the capability of Nano technology accumulated by universities and research institutes with strengths of the existing industries to increase the nation's competitiveness, expanding the function and roles of the association

Nano Technology Research Institute would do our duties devotedly and ask your concerns and advices to the association.

Director's message:
The national program for tera-level nanodevice was established in July 2000 as one of the "21st C Frontier R&D Project" funded by Korea Ministry of Science and Technology (MOST). The aim of the program is to develop tera-level integrated circuit test element group (IC TEG) through overcoming the technological limits imposed upon upcoming semiconductor technologies. This is a ten-year program consisting of 3 phases. The first phase will be operated as a versatile basic cell development for tera-level nanodevices. In the 2nd phase, great efforts will be made for the development of integration process of the nanodevices and the 3rd phase will be concentrated on the development of tera-level IC TEG.

The 21st century is characterized by an information society. To fulfill the final path to this society, every computing system should be flexible, intelligent, mobile, programmable and real-time. Accordingly, computing performance and memory capacity of transistors in the computing system should be more than 1000 fold enhanced with ultra-low power dissipation as compared with present ones. The 1999 international technology roadmap for semiconductors indicates that the tera bit dynamic random access memory (DRAM) is supposed to be developed by the year 2014. This roadmap is based on the assumption that all the necessary technologies are progressively developed on time. Unfortunately, we will face big technological difficulties such as tunneling, RC delay, and thermal dissipation within 5 to 10 years. To tackle these difficulties, joint efforts among industrial, governmental and academic sectors as well as international collaboration are absolutely needed. Our success will revolutionize all aspects of industries and be able to create new industries such as intelligent electronics, intelligent robots, 3-dimensional virtual reality and pocket-size supercomputer.

Finally, I hope this program will grow out to a vivid organization, attacking high-risk ideas and innovative themes with creativity. At present, I am ready to devote myself to leading our program to a great success through collective wisdom and efforts of all our research members, and the supports from the MOST and other parties, both domestic and abroad.

Ever since it was founded in 1938, SAMSUNG has continually refined its mission statement to respond both to change in itself and in the world: "Economic contribution to the nation," "Priority to human resources," "Pursuit of rationalism." Each slogan represents significant moments in SAMSUNG's history, reflecting different stages of the company's growth from a domestic industrial leader into a global consumer electronics powerhouse.

In the 1990's, we once again acknowledged the need to transform our mission statement to keep pace with our growing global operations, rapid changes in the world economy, and escalating competition from well-established rivals.
